Getting the value of Child tags before/after Current Tag

[mac7attack]

Hello all,

Is there any way to test to see if the current child tag is the same as the child tag in the parent before or after the child?

<Questions>
  <question>
    <category>Outlook</category>
     <ask>Some Question</ask>
  </question>
  <question>
    <category>Outlook</category>
     <ask>Another Question</ask>
  </question>
  <question>
    <category>Explorer</category>
     <ask>LastQuestion</ask>
 </question>
</Question>

So using the above xml file and a xslt file, is there a way when processing the second question to test if category tag is the tag as the one above it? I know there should be a position test first to process the first tag differently.
The test should be positive at the second tag and negative on the third.

Thanks in advanced,
Matt

Looks like good. Thanks John

Just one question,
What does template match="@*|node()" do? It look likes it implenting itself again

Thanks
Matt

match="@*|node()" says match any attribute or node, i.e. anything.

The default template in XSL will simply output the text value. The template match="@*|node()" is overriding that and saying output the XML. Its very useful, because when you specify another template (ie match="question") this is more specific and so takes precedence. So you can copy the structure of the orginal document and change a particular node.
